Why D365 F&O Users Should Care About OneLake
For D365 F&O users, OneLake represents a significant improvement over traditional data lakes and the standard lakehouse setup. Here’s why it’s a game-changer:
Simplified Data Management: OneLake reduces the complexity of managing separate data lakes or warehouse architectures by providing a single storage solution that works natively with D365 F&O.
Real-Time Analytics: With seamless integration with Azure Synapse Link, D365 F&O users can access their data in real-time, enabling faster decision-making and insights directly from transactional data.
Cost Efficiency: By centralizing storage and eliminating the need for multiple data management solutions, OneLake can be more cost-effective in the long run, especially for companies that already leverage the Microsoft ecosystem.
Practical Example: Using OneLake with D365 F&O
Imagine you’re a finance manager using D365 F&O to track revenue, expenses, and inventory data. With OneLake, you can store all this data in a central repository without having to worry about the complexities of setting up separate storage solutions. Here’s how it might work:
Unified Storage: Revenue and expense data from D365 F&O, along with external data like CRM records or marketing analytics, are all stored in OneLake.
Advanced Analytics: Using Power BI and Azure Synapse, you can create dashboards that track real-time financial performance, pulling data directly from OneLake without needing to pre-process or move it.
Machine Learning Models: If you want to predict future sales or forecast inventory needs, you can run machine learning models on your D365 data using Azure Synapse directly within the Microsoft Fabric, all while storing the training and results in OneLake.
How Does OneLake Relate to Data Lake and Lakehouse?

Governance | Manual management required | Enhanced governance | Unified security and governance across data sources |
Data Lake Integration with D365 F&O
Data Lakes are a common choice for organizations using D365 F&O, especially with the now-deprecated Export to Data Lake feature (transitioning to Azure Synapse Link). Here's how a data lake relates to D365 F&O:
Storing Raw Transactional Data: Data lakes are often used to store vast amounts of transactional data generated by D365 F&O, such as sales orders, invoices, inventory movements, and other key financial transactions. This raw data can then be processed for more detailed analytics.
Data Exploration and Custom Analytics: With data lakes, organizations can perform data exploration beyond the capabilities of D365’s native reporting tools. For example, combining operational data from D365 F&O with other data sources, like CRM or external sales data, enables custom analytics for deeper insights.
Cost-Effective Storage: For companies with massive amounts of historical data from D365 F&O, a data lake provides a cost-effective solution. It allows for long-term storage without needing to keep all data within the D365 environment, reducing the overall storage costs.
Lakehouse and D365 F&O
The Lakehouse architecture is a more recent approach, addressing some of the limitations of traditional data lakes. Here's how it connects to D365 F&O:
Enhanced Reporting with Synapse Link: As many organizations transition from the deprecated Export to Data Lake to Azure Synapse Link, the Lakehouse model comes into play. It combines the scalability of a data lake with the analytical power of a data warehouse, enabling faster and more powerful analytics on D365 data.
Unified Analytics: With a lakehouse, you can create a single source of truth that combines D365 F&O data with structured and unstructured data from other sources. This means you can generate complex financial reports, manufacturing analytics, or supply chain insights that are more comprehensive than those achievable with D365’s out-of-the-box tools.
Machine Learning and AI: Lakehouses also facilitate advanced analytics like machine learning. For example, using Synapse Analytics or other Azure ML tools with D365 data stored in a lakehouse can enable predictive maintenance for equipment, demand forecasting, or financial risk modeling.
Practical Example: D365 F&O and Data Lake vs. Lakehouse
Imagine a manufacturing company using D365 F&O to manage its operations. They need to analyze production data alongside sales forecasts and customer sentiment data from social media. Here’s how both solutions might work:
Data Lake: The company exports raw production data from D365 F&O to a data lake and keeps it there for historical analysis. The data is then manually cleaned and structured before being analyzed using Power BI or other analytics tools. This approach is cost-effective but may involve time-consuming data wrangling.
Lakehouse: Using a lakehouse architecture (via Azure Synapse Link), the company has near-real-time access to structured production data from D365 F&O alongside other datasets. They can create dynamic reports directly in Synapse or Power BI, with minimal data transformation required. The unified platform supports faster decision-making, enabling the company to respond quickly to production issues or changing demand trends.
